hey guys... my lt1 project i have is messing up. it has been sitting for about a month, and i went to start it today and it was running all crazy. it would fire up, but the tach would not be reading. then all of a sudden it will die.
after that, i would turn the key on and they tack will do a crazy little dance then settle down. i try to start it, and it sounds like it is firing 180* off. it will go back and forth between those 2 things randomly... any thoughts? only thing i can think of is get another ecu. TIA
